De-Enshittify Windows 11: Make Windows 11 More Secure ⭐

Windows 11 offers a mix of security and privacy features, with a recommendation for users to opt for a Copilot+ PC with a Qualcomm Snapdragon X-series processor for enhanced security. Most users log in with a Microsoft account, which provides benefits such as two-factor authentication, device-bound passkeys, account recovery options, and automatic disk encryption. However, using a local account poses security risks, including limited recovery options and lack of support for key security features. To secure Windows 11, users should take several steps during initial setup or later, including enabling Windows Security features, verifying device encryption, and enhancing sign-in security through Windows Hello options like facial and fingerprint recognition. Additional security features such as Controlled Folder Access and Smart App Control can be configured for better protection. Users are advised to remove unnecessary third-party security apps and keep Windows 11 and installed applications up-to-date to maintain security. Regular updates and proper configuration of Windows Update settings are also essential for preventing disruptions and ensuring data safety.

How to Install McAfee Antivirus on Windows 11 or 10

Installing third-party antivirus software like McAfee on Windows 11 can be challenging due to the built-in Windows Security, which can complicate the installation process. Users may face issues such as silent failures from conflicting software, permission problems on restricted machines, or restrictions due to S Mode on new laptops. Windows 11 includes Windows Security, which is effective for malware protection, but McAfee may be necessary for compliance, additional features, or centralized protection for multiple devices. McAfee supports Windows 11 Home, Pro, and Education editions but not Enterprise. The minimum hardware requirements include a processor of 1 GHz or faster, at least 2 GB of RAM (4 GB recommended), 1.3 GB of free disk space, an internet connection for download and updates, and a display resolution of at least 1024×768. McAfee requires a persistent internet connection for activation and updates. Before installing McAfee, users should check if their device is in S Mode, as McAfee cannot be installed in this mode. They must remove any existing antivirus software completely, as leftover files can interfere with the installation. Users should also ensure that Windows 11 is up to date and verify that there is enough disk space available. To download McAfee, users should go directly to the McAfee trial page to avoid scams. After downloading, they need to run the installer and restart their computer after installation. Users should then activate McAfee, run a manual update, and conduct a full system scan. Common installation problems include freezes during download, errors due to S Mode, and issues with Windows Security not recognizing McAfee as the active antivirus. Users can verify that McAfee is functioning correctly by checking the system tray icon, Windows Security settings, and the McAfee dashboard. To uninstall McAfee, users should go to Settings > Apps > Installed Apps, select McAfee, and follow the prompts to remove it. After uninstallation, Windows Security will reactivate automatically. McAfee offers several plans for Windows users, including Basic, Essential, Premium, and Advanced, each with different features and device limits. The Basic plan is suitable for single-device users without additional needs, while families may benefit from the Essential or Premium plans.

Avast Antivirus in 2026: Still Worth Paying For on Windows and Mac?

Ransomware is evolving, and many users in the United States continue to invest in Avast Antivirus as of 2026. Avast, now part of Gen Digital, has shifted from a traditional free antivirus to a comprehensive consumer security suite, which includes three tiers: Avast Free Antivirus, Avast Premium Security, and Avast One. The product lineup features a core antivirus engine, ransomware and phishing protection, a firewall, Wi-Fi inspector, built-in VPN, and performance cleanup tools. Avast's core antivirus engine provides real-time file scanning and web/email shields, consistently ranking high in independent lab tests for malware protection. The ransomware shield protects sensitive folders from unauthorized encryption, while the firewall and Wi-Fi inspector are available in paid tiers. The built-in VPN is designed for safer public Wi-Fi use, and performance tools aim to optimize system efficiency. Pricing for Avast products in the US varies, with a free tier supported by upsell prompts for premium features, Premium Security typically offered as an annual subscription, and Avast One marketed as a higher-value bundle. Renewal pricing often increases significantly after the first year, leading to user complaints. Microsoft Defender is now effective enough that many experts believe average users may not need third-party antivirus software, but Avast justifies its subscription by offering stronger web protection, more control over app permissions, and additional non-security features. User feedback highlights strong protection but frequent upsell prompts, performance issues on low-end machines, and concerns over past data collection practices. Avast is seen as valuable for households with mixed tech literacy, remote workers, students on older hardware, and users seeking basic privacy protections.

New Keenadu backdoor found in Android firmware, Google Play apps

A sophisticated Android malware named Keenadu has been discovered embedded in the firmware of various device brands, compromising all installed applications and granting unrestricted control over infected devices. It employs multiple distribution methods, including compromised firmware images delivered over-the-air, access via backdoors, embedding in system applications, modified applications from unofficial channels, and infiltration through apps on Google Play. As of February 2026, Keenadu has been confirmed on approximately 13,000 devices, primarily in Russia, Japan, Germany, Brazil, and the Netherlands. The firmware-integrated variant remains dormant if the device's language or timezone is associated with China and ceases to function without the Google Play Store and Play Services. While currently focused on ad fraud, Keenadu has extensive capabilities for data theft and risky actions on compromised devices. A variant embedded in system applications has limited functionality but elevated privileges to install apps without user notification. The malware has been detected in the firmware of Android tablets from various manufacturers, including the Alldocube iPlay 50 mini Pro. Kaspersky has detailed how Keenadu compromises the libandroid_runtime.so component, making it difficult to remove with standard Android OS tools. Users are advised to seek clean firmware versions or consider replacing compromised devices with products from trusted vendors.

MyDoom virus: What it is and why it mattered

In January 2004, the MyDoom computer worm quickly spread to email inboxes in 168 countries, becoming one of the fastest-spreading pieces of malware in internet history. It exploited human behavior by enticing users to open email attachments that appeared to be delivery errors or system notifications. MyDoom replicated itself through email without corrupting files or destroying data, harvesting email addresses from infected computers to send copies to new victims. The two main variants, MyDoom.A and MyDoom.B, targeted the SCO Group and Microsoft, respectively, and demonstrated the potential for email worms to be weaponized for coordinated attacks. MyDoom primarily targeted Windows-based operating systems and used deceptive emails to propagate. Once infected, it installed a backdoor for unauthorized remote access, forming a botnet for further attacks. MyDoom's effectiveness was due to its alignment with user behavior and the limited security measures of the time, leading to significant disruptions in email communication and an estimated economic impact of approximately billion. Although no longer a current threat, MyDoom's legacy influenced modern email security protocols, leading to improved filtering, behavior-based detection, and multi-layered defense strategies.
